IMPROVEMENT IN VISES.

Specification forming part of Letters Patent No. 197,083, dated November13, 1877 5 application filed September 22, 1877.

To all whom it may concern:

Be it known that I, AzEL H. BELL, of Belle Plaine, in the county ofBenton and State of Iowa, have invented a new and valuable Improvementin Vises; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of a side view of my vise.Fig. 2 is a plan view, and Fig. 3 a detail view, thereof.

The natureof my invention consists in the construction and arrangementof a vise, as will be hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate myinvention.

A represents the bed of my vise, formed at each end with slotted sideprojections a for the passage of bolts 1), to fasten the same to a baseor lever.

At one end of the bed A is formed an upwardlyprojecting lip, B, whichconstitutes a back support for the jaw G of the vise. This jaw is formedwith a dovetailed tapering tongue or tenon, G, on its under side, whichis inserted from one side into a corresponding groove, 01, formed in thebed A alongside of the lip B, in such manner that when the jaw G isplaced in position the said lip bears against the back thereof, andforms a back support for the same. The tongue or tenon O is of the samelength as the width of the base A, and a lug, e, on the back of the jaw0 forms a stop against the side of the lip B to limit its movement. Atthe other end of the bed A is formed an inwardly-projecting flat hook,E, as shown.

D represents the movable jaw of the vise, formed at its base with arearward extension, D, and at the sides with downwardly-projectingflanges, which'extend forward in front of the jaw in the form of arms DD Gr represents the wedge shaped key by means of which the movable jawis operated, said key having a lug, 13, formed at its smaller end, to.prevent its withdrawal altogether from its place in the hook E.

To put the parts of the vise together, the key G is first placed in thehook E. The jaw D is then placed on the bed A, the side flanges fittingon the sides of the bed. When the jaw D is moved, with its extension D,as far as possible under the hook E, the ends of the arms D will just befree from the groove (1, and the jaw G can then be inserted in saidgroove, as above mentioned, and the vise is complete.

The jaws O and D of the vise are so constructed that their lowerportions will clamp a wire in such manner that it cannot be drawnthrough when tightening up a fence. This construction consists of abulge, m, on one jaw, with a corresponding concavity or recess, n, inthe other jaw, and this does not interfere with the jaws when used asavise.

When using it as a wire-tightener, the bed A is bolted to a lever, andthe vise clamped to the wire. The short end of the lever is placedagainst the end or stretching post, and the wire then drawn taut, andsecured by a staple or other suitable means.

The arms D of the sliding jaw, it will be noticed, pass under thestationary jaw O at the ends of the tongue 0, and not only prevent thestationary jaw from coming out, but also keep the sliding jaw in place,so that when the pressure is on the top edges of the jaws, the slidingjaw cannot tip back.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the bed A, provided with the top B and dovetailedtapering groove d, and the jaw 0, provided with the dovetailed taperingtongue G, sliding jaw D, and the stop 6, substantially as and for thepurposes set forth.

2. The sliding jaw D, provided with the extension D and arms D D incombination with the bed A, hook E, and stationary jaw O, substantiallyas and for the purposes set forth.

3. The combination of the grooved bed A, with hook E and lip B, thedetachable stationary jaw G, the sliding jaw D, with extension D andarms D and the key G, all constructed substantially as and for thepurposes set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

AZEL H. BELL.
